Nancy Seiberling left this life in the early morning hours of January 12, 2015 at Honey Creek Cottage in Swisher, Iowa, after years of struggle with Alzheimer's disease. Her youngest daughter, Angela, was with her in her last hours. For a tribute from her daughter, Grace, please click here.

Before retiring from public life, Nancy was a no-nonsense spokesperson for environmental and social concerns, an organizer who brought the best out of people, and drew them together to work toward a better community. In the college town of Iowa City, where the elm trees that once gave shade to the street were now dying in the 1960s, Nancy Seiberling, working along side Gretchen Harshbarger and Jim Maynard, advanced the vision that trees and shrubs should be an integral part of the city planning, starting Project GREEN (Grow to Reach Environmental Excellence Now). In the coming years ornamental trees and shrubs were planted with the help of hundreds of people Nancy touched, with the help dollars offered by community leaders and townspeople infected by Nancy's enthusiasm. That vision of beautifying and community-building played an important part in making Iowa City what it is today, a vibrant town where aesthetics play a pivotal role in citizens' lives.

Born May 6th 1917 in Minneapolis, Minnesota, daughter of Rebecca and Alton Jackson, Nancy soon moved with her family to Winchester, Massachusetts, where Nancy and sisters, Becca and Dorothy, spent their formative years. In the mid-30s the family was to move to Wellesley so that Becca and Nancy could attend Wellesley College while living at home. (Dorothy, "DJ", went to Colby.) A Wellesley art professor sparked Nancy's interest in art history, blazing the way for the path she would take in life. A year after graduating in 1939, Nancy took a job at the Toledo Museum in art education, there meeting Frank Seiberling Jr., the Supervisor of Education for the museum. The two were married in 1941. While Frank served in the Army and later was finishing his PhD Thesis from the University of Chicago, Nancy remained in Toledo and bore two children, Grace and Franklin. Son, Christopher, was born in 1946 while the family was in transition to a country home outside Columbus, as Frank had been hired as a Professor of Art History at Ohio State University. Angela, the youngest, was born in Columbus. The family was to stay in Ohio until 1959 when they moved to Iowa City.

A family home was to be built in the countryside, overlooking the Coralville Reservoir, north of Iowa City—a home that was to be known as Fairhill, a center for cultural events, as well as family gatherings. When a dance troupe visited the University of Iowa, more often than not a gathering would be held for them at Fairhill; area social organizations held receptions there, and there were musical performances. Between hosting events, community organizing, cultivating perhaps the most exquisite garden in Johnson County, and managing family business, Nancy's days were full, and she worked tirelessly, never seeming tired or overwhelmed. In addition to Project GREEN, Nancy was also a founding member of the Johnson County Heritage Trust ( Now the Bur Oak Land Trust ), formed to protect land of significant environmental value from development, and to encourage responsible land management.

Her life did not slow down until after her husband, Frank, died in 1990, and she moved to a small house on the west edge of Iowa City on a hill above a bend in the Iowa River. There she lived for almost two decades before placement in Honey Creek Cottage near Swisher, Iowa, in March of 2010.
